Abstract

PURPOSE:To easily record frame numbers by inputting the 1st frame number of a negative film with a keyboard, judging and inputting a successive frame number from the quantity of feeding of the negative film, and inputting the frame number again when the quantity of feeding exceeds a constant value. CONSTITUTION:The frame number of the 1st head frame of the negative film 1 such as a piece film and a long-sized film is inputted manually on the keyboard 14. Then a next frame number is judged from the quantity of feeding of the negative film and inputted automatically and when the quantity of feeding exceeds the constant value, the frame number is inputted again manually. Therefore, the cumulative error in the quantity of negative feeding is canceled at intervals of a specific number of frames. Consequently, frame numbers of even a film having no frame number code are judged and the film can be printed on color paper, etc.

Description

[Detailed Description of the Invention] Purpose of the Invention; (Industrial Application Field) This invention records frame numbers on prints made by printing negative film frame images onto photographic paper and then developing them, or on a recording medium corresponding to the prints. This article relates to a method for inputting frame numbers for printers that are designed as follows.

(Prior Art) Generally, when taking a photograph, developing the film, and printing at the same time, and then making additional prints, one searches the film for the frame number of the desired photographic film, and orders additional prints using that number. ing. This also applies to reprinting in a laboratory or the like. The frame number is attached to the edge of the negative film 1 as shown in Figure 6, but when searching for a desired frame and there are many similar photographs, it is difficult to search for the desired photograph on the film. It is difficult, and often requires custom pieces or remade pieces. Furthermore, because it is troublesome to search for the desired photograph on negative film, people often neglect to order extra prints.

Therefore, if the film frame number is printed somewhere on the printed photograph, it will be extremely convenient to reprint or order additional prints.

To print the film frame numbers on a print, you can record the numbers sequentially on the front or back side of the photographic paper in some way during the printing process, but even when printing for photography, you can The frame number of each frame varies depending on the person taking the picture, the camera used, and the method of loading the film. Also, 1.2 of the frame number of the film. . . . etc. may be located exactly between the frames, and in such cases, even if the paper is full size, it must be printed with auxiliary numbers such as IA, IB, etc.

(Problems to be Solved by the Invention) A display method on prints that eliminates the above-mentioned drawbacks is disclosed in Japanese Patent Laid-Open No. 128933/1983.

This detects the amount of film feed from a reference point that indicates a certain position on the film to each frame, and based on this detected amount of feed, calculates the distance from the reference point given in advance to each frame. The frame number of each frame is determined from the relationship with the frame number of each frame, and the frame number is recorded and displayed at an arbitrary position on the print where the frame is printed. However, in the above method, it is necessary to provide a reference point (mark) that can be reliably detected during the printing process, and it is not possible to correct the deviation of the frame number due to incorrect measurement of the feed amount or the like.

In addition, the frame number code attached to the negative film can be OC
There is a method of automatically inputting the piece number by reading it with R etc., but the device is complicated and expensive. Furthermore, if positioning is performed only from the perforations of the negative film, the perforations are widely spaced, so that positioning accuracy cannot be achieved. Especially when two frame numbers correspond to approximately the same amount of frames, sufficient positioning accuracy cannot be obtained.

This invention was made due to the circumstances mentioned above,
An object of the present invention is to efficiently input frame numbers without depending on the frame number code on the negative film, and to easily record the frame numbers on a print or a recording medium compatible with printing. The purpose is to provide a method.

Structure of the Invention (Means for Solving the Problem) This invention relates to a method for inputting a frame number of a printer.
The above object of the present invention is to print a negative film image onto photographic paper using a printer, and then record frame numbers on a developed print or a recording medium corresponding to the print.
The frame number of the first frame of the negative film is input from the keyboard, the frame number of the subsequent frame is input by analogy with the feed amount of the negative film, and when the feed amount exceeds a certain value, the frame number is input from the keyboard. This is achieved by re-entering the number.

(Function) In this invention, the frame number of the first frame of a piece film or long film negative film is input manually from the keyboard, and the next frame number is automatically inferred from the negative feed amount. At the same time, when the feed amount exceeds a certain value, the piece number is manually re-entered.

Therefore, the cumulative error in the negative feed amount can be canceled for every predetermined number of frames, and accurate frame numbers can always be recorded.

(Example) FIG. 1 shows an example of a system to which the present invention can be applied, and a piece or long negative film 1 as shown in FIG.
The color paper 21 is loaded into a predetermined position of O and exposed frame by frame. The exposed color paper 21 is sent to the processor 22 and subjected to processing such as development, and the processed color paper is inspected by the Invector 23 and sent to the printing machine 3.
0, and the NG prints are sent to the printing machine 30 with an NG mark etc. attached to the back side. In the printer 10, frame numbers and the like are recorded on a memory card 20 each time the negative film 1 is exposed, and the recorded memory card 20 is loaded into a predetermined location of the printing machine 30, and the frame number is recorded at the corresponding frame position on the color paper 21. Print. In this case, the printing machine 30 detects the NG mark attached to the color paper 21 and prints out the NG mark.
The prints are sent to the reprinting process. The color paper 21 on which frame numbers are printed by the printing machine 30 is sent to a cutter/sorter 31 and cut into predetermined lengths, resulting in prints 32 classified by negative film IA. The print 32 is then delivered to the customer along with the negative film IA.

FIG. 2 shows the external configuration of a printer 10 to which the present invention can be applied, in which the negative film 1 is loaded in a predetermined location and fed frame by frame, and a frame image positioned in the exposure section 11 is exposed to a light source (not shown) below. ), and the roll-shaped color paper 21 stored in the print section 12 is exposed to light. Further, a keyboard 13 for instructing correction information etc. during exposure, and a keyboard 14 for inputting frame numbers etc. are provided on the desk, and a memory card 20 is provided on the side.
A recording device 15 is provided for loading the frame and recording the frame number and the like. As shown in FIG. 3, the negative film 1 is conveyed by a pulse motor 16 via rollers, etc., and the amount of feed is detected by counting the number of supplied pulses with a counter (not shown). The perforations 2 arranged at regular intervals are photoelectrically detected by a detector 17. Furthermore, negative film 1
A notch 3 provided at the lower edge of the frame to be printed is adapted to be detected photoelectrically by a detector 18.

The method of the invention shown in FIG. 4 will be explained in the configuration as described above. In this example, a piece film with about 6 frames is shown.

First, the negative film 1 is set in the printer 10 (step S1), and the start key is operated on the keyboard 13 to convey the negative film 1 (step S52). Then, it is determined whether or not the frame of the negative film 1 is the last frame (step S3), and if it is not the last frame, it is transported until the notch 3 is detected and then stopped (step S4). The operator judges whether or not the stopped piece is the first piece (step S5), and if it is the first piece, enters the piece number on the keyboard 1.
4 (step S8). Also, if it is not the first piece, it is determined whether it is the sixth piece or not (step S6), l
If it is not the plth one, the negative feed amount is detected from the amount of pulses supplied to the pulse motor 16, and the frame number is estimated and input (step S7). If it is the sixth frame, the frame number is input from the keyboard 14. When the frame number is input and set in this way, exposure data is input from the keyboard 13 (step S9), and then the exposure of the frame is performed on the color paper 21 (step 510).
The number of this exposed frame is recorded on the memory card 20 (step 5ll), the color paper 21 is conveyed by a predetermined amount for one frame (step 512), and the process returns to step S2. The same operation is repeated until the final frame is reached, but the interval between frames to be re-input is appropriately determined depending on the amount of slippage in the negative feed of the printer.

Next, another example will be described with reference to the flowchart in FIG.
This will be explained using a long film as an example.

First, the negative film 1 is set in the printer 10 (step 520), and the start key of the keyboard 13 is operated to convey the negative film 1 (step 521). Then, it is determined whether the frame of negative film 1 is the last frame (step S22), and whether or not the detection M17 has detected perforation 2 is determined (step 523), and if perforation 2 is detected, the first perforation 2 is detected. It is determined whether or not (step 524). The number of negative feed pulses cleared each time the detector 17 detects perforation 2 is P, the negative feed amount per pulse is dF, and the interval between perforations 2 is dP.
Then, the negative feed amount when the first perforation 2 is detected is obtained by L - P X dF (1) (step S25), and the negative feed amount when the first perforation 2 is not detected is L −L + dP
...... It is determined by (2) (step 526).

Next, it is determined whether notch 3 is detected by the detector 18 (step 527), and if notch 3 is not detected, the process returns to step 522 and the above operations are repeated.

Further, if perforation 2 is not detected in step 523, the process skips to step 527. If notch 3 is detected in step 527, the negative feed is stopped, the frame is positioned, and the negative feed amount is calculated as L-L+P.times.dF- (3) (step 530). Next, the operator determines whether or not this stopped piece is the first piece (Step 531), and if it is the first piece, inputs its piece number from the keyboard 14 (Step S33); if it is not the first piece, the operator proceeds to Step 30 above. The frame number is estimated from the required negative feed amount and input (step 532). When the frame number is set in this way, exposure data is input from the keyboard 13 (step 534), and then the exposure of the frame is performed on the color paper 21 (step 535).
), the number of this exposed frame is recorded on the memory card 20 (step S36), and the color paper 21 is
A predetermined amount of pieces are transported (step 537),
The process returns to step S21. The same operation is repeated until the final piece is reached.

In each of the embodiments described above, the re-entered or estimated frame number is once recorded in the memory card 20, and then the memory card 20 is loaded into the printing machine 30 to print the frame number on the printout. However, it is also possible to print directly onto a predetermined position on the color paper 21 using the printer 10. Further, in the example shown in FIG. 5, the negative film is transported while detecting the perforations, but the DX code on the negative film may also be detected.

Effects of the Invention: As described above, according to the frame number input method of the present invention, there is no particular need for a device to read the frame number coat on the film, so frame numbers can be input at low cost. There are no problems with misreading. Furthermore, even for films without frame number codes, frame numbers can be determined and printed on color paper or prints.
